Sigh. I don't know if you've been following invisbility cloak research (you haven't? What are you, living under a rock?), but it appears to have hit a snag. Not the usual, "this-can't-be-done-because-we'll-never-have-the-technology-or-materials" snag that it has hit so frequently in the past. Rather, the Chinese have figured out how to un-cloak things before we were done figuring out how to cloak them in the first place.
They're calling it an anti-cloak. And actually, it's not as devastating a breakthrough as you might think. It turns out that if you can't see what's behind an invisibilty cloak, what's behind it can't see you, either (kind of like the Bugblatter Beast). This "anti-cloak" might help the invisible side get its bearings.
